2 2 The hardest single part of building a software system is deciding precisely what to build. No other part of the conceptual work is as difficult as establishing the detail technical requirements, including the entire interface to people, to machines, and to other software systems. No part of the work so cripples the resulting system if done wrong. No other part is more difficult to rectify later.

5 5 1 Introduction This document provides background information for the rest of the document. It briefly describes the project, the client deliverables, the project milestones, and expected document changes. This project has two phases. The first phase is requirement elicitation which includes the delivery of a detail requirement description and a non-functional prototype of the GUI. Second phase, includes the product specification and process specification and functional system. 1.1 Project Overview The web based meeting scheduler (WMS) is a user friendly tool developed to assists humans in office environments to schedule meetings efficiently. The algorithm used in the distributed meeting scheduler paves way for negotiation of various processes on behalf of their users and comes up with an agreement on a common meeting time that is acceptable to all the users and abides by all the constraints set by the hosts and attendees. The motive of the algorithm is to obtain a solution based on the knowledge it acquires during the process. In summary the Web-based Meeting Scheduler follows a decision oriented methodology that depends on knowledge based approach. The purpose of WMS is to support the organization of meetings and to determine for each meeting request, a meeting date and location so that most of the intended participants shall effectively participate. The principal users of this system are the Meeting Initiator and Meeting Attendees/Participants. It is the responsibility of the meeting initiator to schedule the meeting based on the availability of the attendees along with the constraints expressed by the attendees/participants. The meeting scheduler system shall have the ability to handler several meeting requests in parallel and resolve conflicts. The key functionalities of this system are: Schedule/ plan meetings Monitor meetings, especially held in a distributed environment Re-planning of meetings to support changing user constraints Support conflict resolution Keep participants informed of the meeting schedules and any changes Cancel Meeting 1.2 Stakeholders There are primarily three stakeholders involved in Meeting Scheduler System: 1 Web based company Omni-soft: The Company for which the Meeting Scheduling System needs to be developed. 2 Team Call of Duty: The team responsible for developing the Meeting Scheduling System for web based company

6 6 3 Professor Lawrence Chung: Primarily the facilitator between company and Team Call of Duty. He was responsible for the Phase I requirements elicitation and now acting as a communication point between company and team Call of Duty. 1.3 Project Scope The scope of the system shall include Scheduling the meeting in efficient way. Gathering the feedback from attendee. Cancelling the meeting. Changing the meeting schedule and/or location. Scheduling concurrent meetings in timely manner. Conducting virtual meetings. Confirming the location and time of the meeting. Minimize users effort in co-ordinating and scheduling meetings 1.4 Project Usability Automate the meeting schedule process to enable efficient use of the time and efforts of meeting organizer. Select a date and time according to the availability of the participants. Allocate the location that is convenient to all the participants. Send reminders to the participants about the meeting and any schedule changes. Reorganize and modify the meeting schedule if required. Arrange virtual meetings (audio and video conferencing) in case there are remote attendees. 1.5 Project Deliverables The project is divided into two phases with each phase having two sub-phases. The below table provides on the deliverables in each phase and their corresponding deadlines: DELIVERABLE COMPLETION DATE Preliminary Project Plan Phase 1 Interim Report Final Presentation and Report Phase 2 Interim Report Final Presentation and Report Evolution of this Document This document will be updated as the project progresses.

10 Abbreviations SRS Software Requirement Specifications WMS Web based meeting Scheduler FR Functional Requirement NFR Non functional requirement DR- Domain requirement 2 Project Organization 2.1 Process Model The process used for this project will be an agile methodology, based on empirical rather than defined methods. Agile methods involve planning what one wants and then adapting these plans to the results. It is an Iterative approach where requirements and solutions evolve through collaboration between self-organizing cross-functional teams. We will use UML tools to create the system model and the subsequent breakdown of the design. 2.2 Organizational Structure Project Management Team The Project Management Team is comprised of the Project Leads, Project Manager and chaired by the Project Manager.

The purpose of this system is to support the organization in scheduling meetings by determining each meeting s request, date and location. The WMS system will monitor meetings, plan meetings under constraints expressed by the participants, reschedule meetings based on constraints, support conflict resolutions, and manages all the interactions among participants. It also has the ability to concurrently handle several meeting requests at a time. Being an online system, it can be easily accessed from any computer with internet access, thus removing any constraints of time or place. The system also sends relevant notifications and information to respective users through s. The system will have a user-friendly interface. 3 Managerial Process 3.1 Management Objectives and Priorities The objective of the project is to develop a meeting Scheduler system within allocated time, budget and specified quality. The project is prioritized due to high benefits to the organization. One of the important usages of this project is that it will automate the process of meeting scheduling and thus save the time and efforts of meeting organizer. More benefits will be further discussed ahead. The primary focus of our team is the reliability, usability, and quality. Satisfying requirements and perfecting the product is very important to us. Meeting user's needs is our top goal. 3.2 Assumptions and Dependencies The following will be the major assumptions in this project: 1. Management will ensure that project team members are available as needed to complete project tasks and objectives 2. All project participants will abide by the guidelines identified within this plan 3. Project Plan might change based on new information revealed or issues encountered. 4. Availability of customer for meetings and trainings

14 Constraints The project has the below 3 constraints: Time : Time frame within which the activity should be completed Cost : Cost of developing the system within the estimated budged Quality: Level of quality to be met as per the requirements of the users 3.3 Risk Management The initial Risk Assessment attempts to recognize, characterize, prioritize and document a mitigation approach relative to those risks which can be identified prior to the start of the project. This section outlines the risks identified at the start of the project 1. Continuous stream of requirements changes 2. Business owners may not be available during validation phase; this may affect the schedule. 3. Timeline Estimates Unrealistic or Schedule Slips 4. Level of experience in team 5. Absence of Commitment Level 6. Project Team Availability 7. Physical Location of Team prevents effective management 8. Disk failure all project deliverables and documents will be stored in the groups 3.4 Monitoring and Controlling Mechanisms The following are the monitoring and controlling mechanisms for the risks identified in the project. 1. Continuous review of project momentum by all levels 2. Regularly track and report project progress 3. Redistribute tasks in case of delay in completion prioritizing as per requirement 4. Pre-plan tasks in case the task's complexity had been under estimated before 5. Have clearly identified and usable deliverable 6. Communication of any changes to the requirement being document and communicated to the team. 7. Use of Intranet project website, comprehensive Communications Plan 4 Technical Process 4.1 Methods, Tools and Techniques Method The Method we will be following will have a flavour of agile Methodology, an incremental and iterative approach Tools The tools and applications used by the team for this project: a) Document Development: Microsoft Office Word

15 15 b) Architectural and Design Diagrams: IBM Rational Rose, StarUML, ConceptDraw c) Communication : Google Groups d) Development: Glassfish Version 3 Server, java 1.6, J2ee, Servlets, Sql Server 2005, Ajax, JavaScript Techniques The Techniques we will be using in our project will be focused on Model driven development, Test driven development, and object oriented development. MDD gives architects the ability to define and communicate a solution while creating artifacts that become part of the overall solution. MDD is also comprised of the ability to visualize the domain, such as a business domain, and the generation of implementation artefacts. The Model-Driven Architecture (MDA) defines an approach to modelling that separates the specification of system functionality from the specification of its implementation on a specific technology platform. In short it defines a guideline for structuring specifications expressed as models. Test Driven Design (TDD). With a TDD approach you create a test then write enough production code to fulfil that test. In other words, the tests form your detailed design model (as executable specifications), arguably making TDD a modelling approach. Object Oriented Development (OOD) promises to reduce development time, reduce the time and resources required to maintain existing applications, increase code reuse, and provide a competitive advantage to organizations that use it. 4.2 Software Documentation Software Project Management Plan (SPMP) System Requirements Specification (SRS) Process and Product Specification Vision Document Meeting Scheduled Supplementary Document User Manual 4.3 Project Support Functions Configuration Management :Change requests can be tracked and approved within team s Google Groups website Quality Assurance Verification and Validation Training 5 Work elements, schedule and budget This SOW shall commence on Jan 31 st, 2010 (the Effective Date ) and shall continue until 29 th April, The final demonstration is to be given on April Below are the timelines and Deliverable details.
